I want to correct something a previous reviewer said. This story is *tragic,* not melodramatic. Tragedy is a portrayal of deep sorrow or despair which could have been avoided, melodrama is soap opera he-said-she-said. The mangaka clearly portrayed Simone, the out lesbian, as a mature character above drama. This is why, in one scene, Simone has to pull the tea cup away from her straight? girlfriend.
I blame American television for the problem some people have telling the difference between tragedy and melodrama.
Yes, it is indeed the first published yuri manga. I'm glad that it was, because the mangaka paved the way for yuri to
become a meaningful genre, often more original and more artistic than straight romantic-comedy.
